Topic: Mix-stirs vs O2 (Read 773 times)

I've read many favorable comments about mix stirs for wort aeration. I'm going to run out of spare oxygen bottles pretty soon, so I'd like to know your preferences. Do you prefer mix-stirs over oxygen? In all instances? Do they fit in carboys? Do you buy them from Home Depot or a supplier like MoreBeer?

I just bought the spare paddles for the Mix-Stir & mounted them with a stainless steel bolt & nut on a ~20" long piece of 3/8" stainless steel rod. I use it primarily for aerating must (mead) since my technique for moving the wort from the kettle to the fermenter aerates the crap out of it. Here's a link for the paddles. http://www.midwestsupplies.com/replacement-blades-for-stainless-steel-mix-stir.html It really works well with the must. Cheers!!!

The mixstirs work very well and can get you to 8 ppm disolved O2, and I have one. Some yeasts like more O2, lager yeast for example, and for those I use 1 liter/min O2 for a minute to get to 10 ppm disolved O2. If you search the achives here, Gordon has said that he uses the mixstrir for most ales, and O2 for big beers.
